Shallow subs

[mitchellz71 10+ year member]

just sold my old truck with 2 10" assasins powered by a PG 600.1 and im looking to get my new system worked out. the only thing is most boxes for the crew cab chevys dont allow any deeper then a mounting depth of 5.5". i want this truck to be louder, what subs would yall recommend me? not wanting to spend more then $150 per sub..

thanks,

mitchell

edit- im looking for 2 10s again...

I heard Kickers Shallow mounts are good sub

ive did a lot of research on the subject and the kicker cvt's have great reviews along with the slim pioneer subs. RE audio, JL, MTX, Alpine, all have slim line subs, but i havent been able to find any reviews on them. The RE audio SL slim subs look really sweet! I was faced with the same problem and it was suggested that i buy digital designs 1508's 8 inch subs over any slim or shallow sub, so i did. I bought three of them but never had a chance to hook them up before i traded them. maybe keep that in mind

I have heard the Pioneers before, they do sound good. I however never heard the Kickers, I am curious though....

so many of these threads already made. Just search shallow mount. I actually made one awhile back too.

SI BM is the way to go though.

i found some specs on the sundowns

http://www.audiojunkies.com/blog/1266/

also on the SI woofers, the shallow one is 500w rms, the the mag d2 is 1000w rms? i think i could fit the mag d2, only thing is the say they need 1 ft^3, would poly fill help to make it sound better?

im concerned on how the shallow subs will sound, can they hit lows good?

I like the looks of the BM's flat cones. Just remind me of PPI Pro's *drool*

could those sundowns handle 500wrms? they seems like a pretty good choice

Their rms is 400, so if you are smart with the amp gains, you should be fine.

Something else to try to get out of your mind is that shallow subs won't have any low-end. That's a mis-conception that I suppose goes right along with their appearance. But that's where the stereotype should end. It's just like saying that all deep subs play deep or that all heavy subs are loud.

We dropped 1.25" of mounting depth and 10 pounds off the Mag and we gained low end extension and more output in a small sealed enclosure compared to the previous Mag.

The new BM is geared to combat the biggest of the big boys in the shallow sub market. As with our new Mag, the new BM is chock-full of technology. ...let me see if I can snag up a pic over at audiojunkies.com -

To me the picture looks a little funny because the sub on the right (the BM) should be smaller diameter than the sub on the right (the Mag), but it's not.

The new BM's are projected to have the same amount of low-end as our previous Mag if that tells you anything about the low-end potential of shallow subwoofers.

With shallow subwoofers it really all boils down to two things: ingenuity and good old fashioned subwoofer design work. The main thing about designing something shallow is to consider the distance from the spider landing to the cone. Next eliminate a "cone" by using a flat diaphragm. Say the distance from the top of the spider landing to the cone is 1", that leaves you with the height under the spider to the top plate. Lets say that distance is 1" as well, so you've got 2" of depth so far. Throw in a standard motor and coil and you can have a sub that's less than 4" deep. Throw in an XBL^2 and you're less than 3" deep (same stroke, less motor depth).

Now, I just gave you a rough example, nothing more. I didn't mention parameters at all, which will determine how low the sub plays in a specified enclosure type and size. Let me say that again - I didn't mention parameters AT ALL. But after you get over the "hurdle" of using standard parts to make a subwoofer, it's very easy to make a shallow subwoofer that performs decently. Throw in a lot of neat and very beneficial technologies and you can easily have a normal-depth-subwoofer killer in a tiny package.

The BM's won't be out for a while, as we're still ironing out every single little detail, but if you can wait the BM's will be a formidable oponent in the shallow subwoofer market.

The Sundown's are a really nice subwoofer (available now, and on sale too) if you want something with shallow depth and the potential for good output while sounding really nice. Comparatively they kick butt against their competition price-wise.

so looking at the bms specs on the website, thier rms is 500w correct? any idea what the max is?

also i have plenty of time to get my new system together...
